Prior to the formation of the group, each character had his own adventures in DC's war anthology comics. Captain Johnny Cloud, a Navajo pilot who always destroyed his planes after a mission, had appeared in All-American Men of War #82–115 (1960–1966); the two-man team of Gunner and Sarge had first appeared in issue #67 of the same title (March 1959) before transferring to Our Fighting Forces for a fifty-issue run, #45–94 (May 1959–August 1965). Captain Storm, a PT Boat Commander, had his own title, which lasted 18 issues from 1964 to 1967.[1]

Their first appearance as a group was with The Haunted Tank crew in G.I. Combat #138 (October -November 1969) in a story titled "The Losers". The tank crew had failed to destroy a Nazi radar station and collected the 'Losers'. The men were on their own after surviving separate disastrous battles. The eight-man strong group rallied and returned to the site of the Nazi radar station, demolishing it.[2] Prior to that, Captain Storm, Gunner and Sarge (along with Fighting Devil Dog) had teamed together once before to fight some Japanese naval officers in Captain Storm #13. They got their own series a few months later (January/February 1970), as the main feature of Our Fighting Forces, beginning with issue #123. Their stories as a team were written by Robert Kanigher and illustrated by a variety of artists, most notably Sam Glanzman, Russ Heath, John Severin, and Joe Kubert.

The group served in Europe, Africa, and the Pacific, meeting other DC World War II characters such as the Haunted Tank and Sergeant Rock. The team briefly had a female member named Ona Tomsen who was part of the Norwegian resistance movement, who joined the team in issue #135. At the same time, the team briefly lost Captain Storm, who suffered amnesia (and lost an eye) due to a bomb blast. They reunited in issue #141, when Capt. Storm reappeared as a one-eyed, peg-legged pirate. Gunner's pet dog Pooch also joined the team for some missions.

Robert Kanigher was the original writer for the series, and he emphasized the group's bad luck. They were anti-heroes, and the stories emphasized negative aspects of war. During the Vietnam War, Kanigher added this philosophy to many of the DC war books. Also in common with most DC war books of the time were spectacular cover illustrations by Joe Kubert. Ken Barr did the art chores for the first issue, with Ross Andru and Mike Esposito participating beginning with issue #124. John Severin, a veteran of Marvel Comics' Sgt. Fury and his Howling Commandos began doing the art chores by issue #132. This series lasted until Jack Kirby became artist/writer with issue #151 during the autumn of 1974.[3] While Kirby enjoyed working with the series,[4] he changed the story's philosophy in a manner that was often disfavored by fans, judging by comments in the book's letter pages. There have been favorable comments about his series in recent years[5][6] and DC released it in collected form.[7]

With issue #163 Bob Kanigher was back writing the book with Jack Lehti doing the art. For issue #164, Ric Estrada penciled and George Evans inked, and Evans did all of the artistic duties by issue #166. He continued with the series until the final issue, #181 (September/October 1978). A story that was originally set to feature in issue #182, written by Kanigher and drawn by Evans and entitled "Young Losers - Young Lions", was finally printed four years later in The Unknown Soldier #265 (July 1982).

The re-ordering of the DC Universe resulted in a different ending for the team. In The Losers Special #1, written by Kanigher and illustrated by Glanzman, the Losers (along with Pooch) died in action during 1945 while destroying a German missile site: Sarge was bayoneted, Captain Storm fell on a grenade, and the remainder were strafed by aircraft bullets. The Special was published during 1985, during the Crisis' initial printing, and remained the definitive ending of the group for several years.[9]

In 2000, a short-lived revival of the Creature Commandos resurrected Gunner as a cyborg warrior member of the new team.[10] Gunner and Sarge are found alive and out of their own time in an issue of Birds of Prey, trapped in a POW camp in the time-fluctuating Dinosaur Island, now with a "Pooch" that is a trained Velociraptor. It is not known if they somehow went back in time to conclude their lives or if this brings them into the present.

An alternative ending was presented in the out-of-continuity 2004 miniseries DC: The New Frontier. In it, the group was sent to Dinosaur Island during December 1945 to rescue Rick Flag and important war-time information. Once they go on the island, one by one, they are killed due to the dangers of the island. Gunner is smashed by a Tyrannosaurus rex. Storm is snatched by flying beasts. Sarge vanishes while trying to kill the same Rex. Pooch is hit by a booby trap set by Rick Flag. Johnny Cloud, after ensuring Flag can conclude the mission, sacrifices himself in a revenge mission on the same T-Rex. Their epitaph, of sorts, was written by Johnny Cloud: "Ask my family and they'll tell you I was a Navajo. Ask the Army Air Force and they'll say I was an American. But if you ask my brothers, they'll set you straight. John Cloud was a Loser."[12]

A new The Losers series began during 2004, created by writer Andy Diggle and artist Jock and published under DC's Vertigo imprint. The new series, set in the present, concerns a team of special forces soldiers who declare war on the Central Intelligence Agency after their Agency handler tries to assassinate them.[13] It was initially inspired by and intended to be a continuation of the original series, with the unit having survived their final mission and getting back together in the 1950s for a caper story.[14]

In 2010 DC published five one-shots featuring characters and titles revived from their "classic" war comics line, including Our Fighting Forces, featuring The Losers. The one-shot was written by B. Clay Moore and drawn by Chad Hardin and Wayne Foucher. The story featured the "classic" team of Johnny Cloud, Captain Storm, and Gunner & Sarge.

In the Flashpoint universe, Gunner was a member of Team 7, an elite unit of soldiers lead by Grifter. Gunner and most of his teammates were ultimately killed during a botched attack on a Jihadist training camp.[15]

Scribe Robert Kanigher and artist Russ Heath turned these self-described Losers - including "Navajo Ace" Johnny Cloud of the U.S. Army Air Force, Marines Gunner Mackey and Sarge Clay, and Captain William Storm, a PT boat commander with a prosthetic leg - into a fighting force that meshed as one.

^McAvennie "1970s" in Dolan, p. 161: "Jack Kirby also took on a group of established DC characters that had nothing to lose. The result was a year-long run of Our Fighting Forces tales that were action-packed, personal, and among the most beloved of World War II comics ever produced."
